  • Security bolt
    Patent number: 9091291
    Abstract: The present invention relates to a security bolt understand a threaded bolt screw body (2) topped by an intermediate part (4) and a bolt head (3), joined together by weakened connections links (5, 6), the weakened connection (5) between the intermediate part and the bolt head torque being less resistant to torque than the weakened connection (6) between the intermediate part (4) and threaded body (2). A cap (8) covers the bolt head (3), the intermediate part (4) and the two weakened connections (5, 6), and is engaged in its lower region with a ring (7) positioned below the intermediate part, around the threaded body (2). The top surface of the cap (8) is formed with an lower formation (12) that cooperates with a formation (13) on the bolt head (3) to transmit rotation of the screw body. After a torque threshold, the first weakened connection (5) breaks, allowing the cap to rotate without transmitting the rotation to the screw.
